SQL S-
METER
A special SQL (Squelch) S-meter feature is provided on this radio. This feature allows
you to set the squelch so only signals exceeding a certain S-meter level will open the
squelch.
To set up the S-meter squelch feature for operation, use the following procedure:
1. Press and hold the
key for one second to enter the Set Mode.
2. Rotate the DIAL knob to select Set Mode Item 93: SQL S- 93: SQL S- 93: SQL S- 93: SQL S- 93: SQL S-
METER METER METER METER METER .
3. Press the key briefly to enable selection of this Set Mode
Item.
4. Rotate the DIAL knob to select the desired signal strength
level for the squelch threshold (LEVEL1 LEVEL1 LEVEL1 LEVEL1 LEVEL1 - LEVEL9 LEVEL9 LEVEL9 LEVEL9 LEVEL9 or OFF OFF OFF OFF OFF ).
5. When you have made your choice, press the PTT switch to
save the new setting and return to normal operation.
1) When the SQL S-meter is activated, the S-meter segment corresponding to
the squelch threshold which was set by step 4 above will blink.
2) The receiver’s squelch will open based on the higher of the levels set by the
Noise Squelch or the S-meter Squelch system.
For example:
a) If the Noise Squelch (SQL control) is set so that signals at a level of “S-3” will open
the squelch, but the SQL S-meter (Set Mode Item 93) is set to “LEVEL 5,” the squelch
will only open on signals which are “S5” or stronger on the S-meter.
b) If the SQL S-meter is set to “S3,” but the Noise Squelch is set to a high level which
will only pass signals which are Full Scale on the S-meter, the squelch will only open on
signals which are Full Scale on the S-meter. In this case, the Noise Squelch overrides
the action of the S-meter Squelch.
